FRANCIS SGHAEFFER, OF MOHNTON, PENNSYLVANIA I-IAT-FELTING MACHINE.

Application filed December 26, 1924. Serial No. 738119.

This invention relates to improvements in felting machines of the character in which the material to be felted is confined between rollers which moisten and exert pressure on the material.

The primary object of the invention is to provide a felting machine of this type in which one of the rollers is formed in a plurality of sections, means being provided to alternately raise and lower said sections to permit the same to pound the material.

A further object of the invention is to provide means whereby the operator may simultaneously raise all of the sections of the sectional roller to permit the material to be placed between and to be removed from the rollers.

Another object of the invention is to furnish a machine of this character with adjustable means to vary the alternate raising and lowering of the sections of the sectional roller, whereby the force of the pounding action may be regulated.

Vith the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accom panying dran' i'n gs and more particularly pointed out in the appended claims.

Referring to the drawings: Figure 1 is a longitudinal vertical sectional view of the apparatus taken on line 1 1 of Fig. 4.

Fig. 2 is a side view of the same. Fig. 3 is an elevation of the opposite side of the machine.

Fig. f is a top plan view.

The machine comprises a frame 5 supporting a tank 6 to contain water or the like, and a heating coil 7 may be arranged in this tank to heat the water and generate.

in the "tank for the purpose of directly applying moisture to the material undergoing treatment. I

Each of these rollers has a. driven shaft which is journale'd in the sides of the frame 'ered by a ca'sin and all of the rollers are driven in the same direction by gears 11 mounted on the ends the shafts and meshing with idle gears 12. These gears are driven from the main pivot shaft 13, and they are preferably cov- The shaft 13 supports a plurality of arms 14 which are 'piv'otally mounted on the shaft and carry the sections 15 of "the sectio iral pressure roll at the forward ends. These sections 15 are arranged 'to be raised and lowered into the space 16- between the bed rollers, so as to pound the material confined between the rollers. Each section 15 of the pounding roller is positively driven from the shaft 13 by means of bevel gears 1'7, 18, a shaft 19 and bevel gears '20, 21, and the COnStFuCtiOn is such that each section 15 is continuously driven regardless of the position of the arm 14 relatively to the shaft 13.

As stated above, the sections 15 of the pounding roller are alternately raised and dropped and tocause this movement, each arm 1 1 is provided with a tail-piece oriug '22 which are struck by oppositely extending cams 23 fixed on a rotatable shaft 2 1. This shaft, as best shown in Fig. 2, is provided at one end with a 'worm gear 25 driven by a worm 26 on a shaft '27, the latter having a bevel gear 28 meshing with the gear 17. The parts 24, 25, 26, 27 and 28 are mounted in a frame 29 which is pivoted 0n the shaft 13, so that the shaft 2 1 may be swung relatively to the shaft 13 to bring the cams 23 toward or move the same away from the lugs 22, and due 'to this construction the extent of the raising of the sections 15 of the pounding roller may be varied.

As best shown in Fig. 1, the pivoted frame 29 is provided with fixed quadrant racks 30 each of which meshes with a gear 31 fixed on a shaft 32. Asshown in Fig. 3, the shaft 32 is provided at one end with a fixed gear 33 that meshes with a worm 34 on the shaft 35, which "carries a hand wheel 36. It is obvious that when the hand wheel 36 is turned, the worm 34 will actuate the shaft 32 and this will cause the gears 31 to move the quadrants 30 and rock the pivoted frame 29, so that the shaft 2 1 will be shifted, and its cams 2-3 will be brought to a desired position for striking the tail-pieces '22.

As mentioned above, both sections 15 of tions 15 to be controlled manually, the lever 37 is connected to a link 38 which pivotally engages a second lever 89 fixed on a rock shaft 40. The latter, as best shown in Fig. 3, is provided at its outer end with a gear 41 meshing with a worm 42 on a shaft 43 having a hand wheel 44. It is evident that when the wheel 44 is rotated in the proper direction, the worm 42 will cause theshaft 40 to move and swing the lever 39, and that this lever will cause the lever 37 to rock and raise both arms 14. 7

It is believed fromthe foregoing, that the construction, operation and advantages of the invention may be readily understood, and it is apparent that changes may be made in the details disclosed without departing from the spirit of the invention as expressed in the claims.

While the rolls 15 are described as employed in pounding the material, it is obvious that they may be also employed as simple rotatingrolls resting upon the ma terial in space 16 and acting on same ointly as would a single roller, the earns 23 in such case being moved by hand wheel 36 so as to entirely clear the tail pieces 22; such selective rolling and pounding actions greatly increasing the capacity andusefulness of my improved construction for a great variety of. work.
